There are so many choices, and all of them promising a quick entry into dreamland.
I've pretty much tried most types. Still, my favourite pillow is feather-filled.
What I like about a feather pillow is that I can re-position the feathers where I need them to provide - with a bit of bunching, clumping and squishing - support.
